Answer provided by our tutors
Let
a = the charge for each adult
c = the charge for each child
The tickets for 1 adult (Mr. J. Raff) and 2 children cost $8.75 means:
a + 2c = 8.75
The tickets for 2 adults (Mrs. Ella and Grandpa) and 5 kids cost $19.75 means:
2a + 5c = 19.75
We have the following system of equations:
a + 2c = 8.75
2a + 5c = 19.75

........
a = $4.25
c = $2.25
The zoo charges $4.25 for each adult and $2.25 for each child.
